Application filed August 8, 1919.` Serial-Nor: 81230w To all ul/wml t may concern.'

it known that il, ARTHUR E. F oLsoM, Va. citizen of thejllnited States, residing at Y `Niuchendom in the county of lllorcester and State of llassachusetts, have invented an Impro vement Vln llaning-h/lachines, of which the following description, iny connection withthe aecompanying drawings, is a speci'cation,A like characters on the drawings representing like parts. j

The invention to be hereinafter describedl` relates to' wood planing machines, and is an 'in'lprovement upon the machine shown, de-

scribed and claimed in my copending application. Serial No. 11i-8,860, filed February 15, 1917. l

The machine of said application comprises a frame having a rotary cutter mounted thereon and feed rolls for feeding the work Y gaging member, and devices are provided'A for clamping the bridge and work engaging member together to secure the same in dit- Iferent positions of adjustment.v

The aforesaid construction constitutes a good, efficient form of means for the pur-Y pose, but said construction is susceptible `of certain improvements.

One of the/objects of the present invention to provide a bridgemember and a work engaging member Vwhich will be simpler and stronger in construction, and better'able toy stand up under the heavy duty of holding the workin therproper relation to the rotary cutter. Y

Another purpose of the invention is to provide simpler and more efficient means for Vedecting the relative adjustment of the 50l bridge-member and work engaging member, and simple and efficient means which shall be readily accessible and easily operated for the purpose of clamping the bridge member and work 'engagingmember together in different positions of relative adjustment.

An adjusting In the use of the machine it is frequently desirable toobtain a slight variation in the pressure of the workl engagingf member against the work, and therefore, it is desirn able to be able to obtain a nicety of relative adj ustmentof the bridge member and work engaging member. Y Another purpose of the invention, therefore, is to provide an indexv and scale which will readily enable a slight relative' adjustment of said parts from -a previous adjustment, and which willY indicate the direction of adjustment necessary to move a work engaging' member toward o1' from' the work.

lVith the aforesaid fand other objects in view, the character of the-invention will be best understood by reference to the following description of one good rform thereof shown in the accompanying drawings, wherein Figurey 1 is a vertical longitudinal'section through a wood planing machine embodying the invention;

' Referring to the drawings, the wood planing machine shown' 'therein may have any suitable frame or support for the operating parts of ,theV machine.YAY In the'present in` stance of the invention, a pair of side frames, such', for example, as the side framel are provided, and are held inproper spaced relation by suitable transverse members. To" support the work, a table 3 is provided eX- tending between and mounted on 'the' side l frames. Y Y

To feed the work along thertable, a pair of Vupper and lower in-fe'ed rolls 5 are provided.

The lower roll has a shaftf? journaledz in` boxes 9 mounted on the side frames of the l machine beneath the table, and the-upper. feed roll has ashaft 11 journaled'in boXes adjustable vertically in guides in the side frames of the machine, said boxesl being pressed downward by coil springs 13 confined between the upper ends of said boxes and yokes 15. A pair of upper and lower eut-feed rolls 17 are provided, the lower roll having a shaft 19 journaled in bearings in boxes 21 mounted in side plates of a carriage Q2 to .be referred to. 'lf he upper out-feed roll 17 has a shaft 3 journaled in bearings in boxes 25 adj ustably mounted in guides in the side fra-mes, and pressed downward by coil springs 27 confined between the upper ends of said boxes and yokes 29.

The in-feed and eut-iteedrolls may be provided with suitable driving means well known in the art, and therefore, it is un 'necessary to show and (escribe the same herein. l

A rotary critter' 31 is mounted on a shaft 33 journaled in bearings on the carriage 22 referred to. lThis carriage may be raised or lowered to raise and lower the cutter and the lower out-toed roll 17 to vary the depth et the cut in the work as desired. The elevation of the carriage may be regulated by wedges 35 beneath the carriage and adjusted by devices 37. Since these wedges and adjusting devices are well known in the art, itis unnecessary further to show and describe the same herein.

Next will be described the means opposed to the cutter for holding the work in proper engagement therewith while the work is ted past the cutter by the in and out-feed rolls. This means, in the present instance et the invention, comprises a bridge member 3) located between the in and out-iced rolls, and having ends l1 adapted to be supported on the opposed side trames of the machine.

lt is desirable to adjust the bridge member with respect to the side iframes for purposes ot preliminary adjustment. To accomplish this, in thepresent instance, a pair of adjusting screw bolts i3 are provided for each of the ends d'1, and are threaded in tapped holes in said ends. The lower ends of these screw bolts may rest upon the upper edges of the side trames of the machine, as will be noted in Fig. 1. By adjusti'nent ol' said screw bolts, the bridge i' einber may be raised and lowered as desired, and one end of the bridge member may be raised or lowered more than the other according to conditions as required. To secure the bridge member in its dilierent positions of adjustment, screws 45 may be provided having their lower end portions threaded into tapped holes in the side iframes, and smooth portions adapted to project upward through smooth holes in the ends 41 oit the bridge member. The upper end portions of the screws -lz may be threaded'to receive securing nuts 17. Alfter the bridge member has been adjusted with the elevation desired, the nuts 47 may be tightened against the upper face of the bridge member and press the adjusting bolts against the upper edges of the side frames of the machine. the bridge member may be securely held in different positions of adjustment. Beneath the bridge member is a work engaging member 119 having a work engaging under tace 51 which may be transversely rounded somewhat to facilitate feed of the work past the same. At the opposite ends of the work en gaging member are upstanding flanges 53 having inclined upper edges 55. Coperating with the upstanding ianges 53 are flanges 57 projectingl downwardly on the bridgemember. These downwardly extending lianges have lower inclined edges 59 opposed to and engaging the' upper edges 55 of the upstanding flanges of the work engaging member. To prevent lateral relative movement between the bridge member and work engaging member, the former may have tongues 6,1 entering grooves 63 on the latter. The construction is such that when the work engaging member is adjusted The construction is such that transversely of the machine with respect to the bridge member, it will be moved downwardly toward the work or upward from the work depending on whether the 'work engaging member is adjusted toward the right l or toward the left of Fig. 2.

-upper end thereof which enters a box 67 on and integral with or rigidly'secured to the bridgevmember. The boX is of suiicient length to allow the post to move toward and from the ends thereof in effecting the adjustment ot the work engaging member. rit the opposite ends oit the box G7 are lugs 69 having holes tapped to receive adjusting screws 71. The construction is such that these screws may be adjusted to push the post along the box and impart the degree of adjustment desired to the work engaging member. '.lhe ends of the screws freely engage opposite edges of the post, and do not interfere with up and down movement of the post with the work engaging member in the course of the adjustment of the latter transversely of the machine frame.

iis stated, one 01"' the purposes of the invention is to provide means for indicating the adjustments elA the work engaging mem" ber. vThis means, in the present instance, comprises an index 73 projecting upward :trom a plate 75 secured by screws 77 to the upper end or' the post. Cooperating with this inde-X is a scale 79 comprising graduations marked on a plate 81 secured by screws 83 to a lug 85 on the top of the boX 67. rlhe index 73 projects upward through Lasa-71m anelongated aperture 87 in the top ofy the.l

boX infront of the sea-le 79. The-construe tion is such that the indexfmoves with the work engagingmember alongzthet scale, and by reference .to thje graduations vof the scale the work engagingmember may be. adjusted with desirabley nicety vof' adjustment.

to indicate the direction of adjustment-A of the workengagingmeniberto causer-lie same to moveI up or down. I i Y Next will be,l described the means for securing the work engagingmeniber touthe bridge member inl different positions of relative' adjustment, and kpreventing lost motion Vbetween said parts. This means, in. the Apresent instance, comprisesa pair of securingposts 87 rising from the work` engaging member ladjacent each` end thereof: These posts project: through elongated apertures 89 surrounded by bosses 91 projectingup-4 ward from-the bridge member, and the Vtops of said bosses have an inclination 4corresponding to the inclination' ofl the enga-ging.; edges of theianges of the bridge memberand work engaging member. Proj ecting; upward from the securing; post 87 are screws 93 entered loosely through holes in bars 95 resting on the upper inclinediedgesof the bosses 91.V The upper end portionsof the screws 93 are threaded to receive nuts 97 adaptedto be adjusted into tight engagement with thc bars 95. can not turn, the nuts on being tightened into i engagement therewith, will be prevented from working loose.

`The construction is such thaty whenit isf desired to adjust thev work engaging member relative lto `the bridgelmember, the nuts 97 are released and then the adjustingscrews 71 are vadj usted as described to move the work engagingl member transversely of the ina-A I chineand thereby obtain the elevation of the work engaging i'nembervdesired. After the work engaging member has been thus adjusted, thenuts 97 may be tightened, thereby .D .to draw the yupstanding flanges of the work engaging member up into tight engagement with the downwardly projectingflanges of ,the bridge'member. Thus, the work engaging member may be securely held to the bridge member, and if the inclined edges of theV flanges of said members become worn,

f the nuts 97 will always insure engagement of the edges of said flanges without lost motion.

In use, the bridge member may be given a vpreliminary adjustment with respect to the side frames of the machine, in order preliniinarily to position the work engaging member with respect to the work, and then the work engaging member may be adjusted as described to :furnish the desired nicety of final adjustment to secure thev necessary engagement of the work engaging member The scale plate may have arrows and the word? to raise7 and to lower. markedv thereon Sincev thevba'rs 95 withthe work properlyto hold the work to the cutter.

By I my invention, simple and eflicien-tY means is` provided for holding thework.'

properly4 to the cutter. Theadjustments of the work engaging member may. be quickly andreadily effected, and saidmeinber may-l be positivelyl heldin its different positions of adjustment. f y It-will beunderstood that the inventionis ynot limited to thel speciiie embodiment shown,
